The RS series (backpack type) has been added to the full self-consumption solar power generation system PPSCⓇ series, allowing for the integration of the power conditioner. This enables one-stop installation of the power conditioner, transformer, and protective devices. With control transformer technology specialized for solar power applications, along with lightning surge protection and leakage current prevention features, it allows for 100% utilization of solar energy, enabling highly efficient energy generation with low standby power consumption. = Benefits of adopting the RS series = ■ Space-saving with PPSCⓇ series + power conditioner ■ Significant reduction in time previously spent on separate installation and construction of power conditioner, transformer, and protective devices. ■ No need for wall drilling work ■ Elimination of installation and logistics costs, as well as time loss in construction periods ■ Reduction in logistics costs due to decentralization ■ Voltage conversion ■ Leakage current prevention (prevents unnecessary operation of the permanent magnet on the cubicle side) ■ Lightning surge protection feature ■ High efficiency and low standby power ■ Specification of core material (amorphous or electromagnetic steel plate) is possible ■ Heavy salt damage resistance (optional)

The 'SPI® Series', which incorporates SPI® transformers (DC current leakage prevention transformers), is designed for connecting to low-voltage distribution lines in industrial solar power generation systems aimed at selling all generated power. By implementing DC current prevention functions, it enables clean power supply (202V) to the grid. Additionally, the S series (amorphous) transformers, which reduce standby power at night, are also available, allowing you to choose according to your needs. SPI® Transformers / SPI® Insulated Transformers for Solar Power Generation 【Features】 ■ Complete isolation between the power conditioner and the grid ■ Voltage conversion (converts the output voltage of the power conditioner PCS to a low-voltage wiring voltage of 200V) ■ DC current leakage prevention function ■ Lightning surge prevention function ■ High efficiency and low standby power *For more details, please download the PDF or feel free to contact us. ◇ In the event of a power conditioner failure, the SPI® transformer (DC current leakage prevention transformer) is crucial for addressing DC magnetization issues in pole-mounted transformers. If a failure in the reverse conversion device (power conditioner, inverter) causes DC components to superimpose on the AC current flowing into the grid, the pole-mounted transformer will become DC magnetized, adversely affecting the voltage for consumers other than those with distortion-dispersed power facilities.

The transformer developed for the purpose of complete self-consumption of solar power, the PPSCⓇ series (Photovoltaic Power Self-Consumption), protects the power generation equipment by completely isolating the power conditioner (PCS) from the grid and power supply, improves power generation efficiency, and prevents the issue of reverse flow, which is a challenge in effectively utilizing solar energy, through real-time tracking control. The "PPSCⓇ transformer," with lightning surge protection and low standby power performance, simplifies equipment installation by integrating "protection devices" and "control devices" as a system. It allows for flexible combinations into high-capacity self-consumption systems according to installation space and purpose, and can also accommodate harsh installation conditions such as salt damage. By constructing systems tailored to the characteristics and specifications of each power conditioner (PCS) manufacturer, it enables the proper equipping of power generation facilities. Additionally, it can also accommodate the "RS series," which features integration of the transformer housing and power conditioner on a dedicated frame, resulting in space-saving, reduced construction time, and significant cost reductions. Please consult us according to your installation environment.

The control transformer (transformer) technology specialized for solar power applications by Kurata Electric Co., along with lightning surge protection and leakage current prevention features, enables 100% utilization of solar energy, allowing for highly efficient energy generation with low standby power consumption without waste. By integrating the PCS (Power Control) rack, transformer, and protective devices, installation costs and time are significantly reduced! = Advantages of the RS Series = ■ Space-saving with PPSC® series + power converter ■ Reduced logistics costs due to decentralization ■ Voltage conversion ■ Leakage current prevention (prevents unnecessary operation of the permanent electric device on the cubicle side) ■ Lightning surge protection feature ■ High efficiency and low standby power ■ Core material specification (amorphous and electrical steel sheets) is possible ■ Heavy salt damage resistance (optional) In addition to the benefits of introducing emergency power generation equipment, it can be installed without wall mounting of the power converter (PCS), avoiding concerns about airtightness in important buildings and insufficient wall strength. ◇ Benefits of Introducing Solar Power Generation ◇ - No fuel required, reducing running costs - When used in conjunction with storage batteries, not only does it receive subsidy support, but the power generation effect and efficiency are significantly improved. - Can be installed by effectively utilizing unused spaces such as roofs.

The PPSC series of solar power generation allows for power procurement independently, even without electricity from the power company or fuel. It efficiently utilizes the solar energy generated. In the event of natural disasters such as earthquakes and floods, as well as conflicts, terrorism, or unexpected crises, it is not an exaggeration to say that preventing business shutdowns and quickly restoring operations to minimize the impact on the business is a lifeline for companies. Implementing BCP measures tailored to the company is crucial for protecting employees' lives during emergencies like natural disasters, reducing damage as much as possible, and quickly resuming business operations. It is important to prepare with awareness for securing power sources for disaster situations and restoring power within approximately one week. Not only does this facilitate early business resumption, but it also enables power sharing during disasters within the local community. By integrating "PPSC Transformer" + "Protection Devices" + "Control Devices," the self-consumption type solar power generation PPSC simplifies equipment installation and can build a self-consumption system according to installation space and purpose, even in harsh conditions such as salt damage. During power outages, power is supplied from solar generation, and surplus electricity is stored in batteries. For a battery system that can be used even at night, please refer to the OFGS series.
